The same output file may not appear more than once. |

Commands are given in quotes, and begin with an exclamantion point ('!'). |

At most, one command may reliably write to its standard output, and |

doing so is incompatible with |

In the case of the |

greater than zero write multiple fields per record to the same stream. |

If the terminating character is set to something other than newline ('\\n'), |

a newline is added after each record (in addition to the terminator). |

For binary output formts, no number implies one value per output. |

The default tab separator |
